In place of a V clip (included in every U-nitt rain chain product), this gutter adapter adds a professional look and functionality to your rain chain installation. It helps improve water flow and minimize splash while providing a stronger link from rain chain to the gutter. U-nitt introduced its name to North America in 2007, with innovation, quality and selection. in the past 5-years, U-nitt discovered the beauty of Japanese old tradition garden rain chains and redesigned them to work with our rain gutter systems and weather elements with added functionality. Each U-nitt rain chain measures 8.5 ft. L with a V clip included for easy DIY installation. Please note the ladder is not included. Copper or aluminum rain chains are made from heavy-gauge metal sheets. Links/cups are removable for adjustable length. Please contact U-nitt for service, parts, comments or questions. It is normal for Original Unfinished Copper rain chains to get spots after 4-weeks-6-weeks of use and start tarnishing with weather and slowly turn to a natural patina look sometimes green and sometimes darker depending on the weather. Changing color is a natural process and a sign of originality. Please rest assured that your purchase is backed with our 1-year manufacturer warranty.
